With just 215g of weight, The Kask Protone has the lowest drag and the fastest heat dissipation coefficients compared to any other ventilated helmet. Thanks to several ventilation holes and a thick padding material, heat and moisture are dissipated very fast, improving comfort and performance without giving up on safety: the top area is reinforced with an internal plastic sub-structure that increases crash protection.
Meets Standards: AS/NZS 2063
Sizing: The size of the KASK helmets corresponds to the circumference of your head! You can use a tape measure positioning it just above the ears, and taking note of the measurement in centimetres.
